13．Among all the fast growing science and technology，the research of human genes，or biological engineering as people call it，is drawing more and more attention now．Sometimes it is a hot topic discussed by people．
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with，such as cancer and heart disease．Every year，millions of people are murdered by these two killers．And to date，doctors have not found an effective way to cure them．But if the gene technology is applied，not only these two diseases can be cured completely，bringing happiness and more living days to the patients，but also the great amount of money people spend on curing their diseases can be saved，therefore it benefits the economy as well．In addition，human life span （寿命） can be prolonged．
Gene technology can help people to give birth to more healthy and clever children．Some families，with the English imperial （皇家的） family being a good example，have hereditary diseases．This means their children will for sure have the family disease，which is a great trouble for these families．In the past，doctors could do nothing about hereditary diseases．But gene technology can solve this problem perfectly．The scientist just need to find the wrong gene and correct it，and a healthy child will be born．
Some people are worrying that the gene research can be used to manufacture human beings in large quantities．In the past few years，scientists have succeeded in cloning a sheep，therefore these people predict that human babies would soon be cloned．But I believe cloned babies will not come out in large quantities，for most couples in the world can have babies in very normal way．Of course，the governments must take care to control gene technology．
8．What does"them"in the second paragraph refer to？D
A．People with cancer or heart disease．
B．Millions of people with serious diseases．
C．Some diseases doctors can do nothing with．
D．The two illnesses of cancer and heart disease
9．What can gene technology do according to paragraph three？D
A．It can help the English imperial family out．
B．It can be used to clone human babies．
C．It can help people to give birth of a baby．
D．It is likely to treat hereditary diseases．
10．What are people worried about according to the passage？A
A．Human babies may be cloned in a large scale．
B．Healthy human babies will soon be cloned．
C．Scientists may well find the wrong genes．
D．The government may not control gene techs．
11．This passage is mainly written toA．
A．show gene technology will benefit people
B．show gene technology will do harm as well
C．tell that gene technology is a hot topic
D．tell that gene technology is growing fast．

4．British society is considered to be divided into three main groups of classes-the Upper Class，the Middle Class，and the Lower or Working Class．This is known as the Class system and it is important to know something about it if you want to understand British people and society．Most British people grow up with a deep knowledge and understanding of the class system even if they are not very conscious（意识到）of it．Most people know which class they belong to by the way they speak，their clothes，their interests or even the type of food they eat．
Social class is not only about behavior and attitudes．For example，although many upper class people are rich and may own a lot of land，having a lot of money does not make a person upper class．It is also important to come from a particular kind of family，have friends who are considered suitable，have been to a certain type of private school and speak with the right kind of accent．There are people who are poor but who do not think of themselves as working class，because their family background，education，political opinions，etc．are different from those of most working-class people．Many people do not like the class system but it is impossible to pretend that these differences do not exist or that British people do not sometimes form opinions in this way．

1．We now think of chocolate as sweet，but once it was bitter．We think of it as a candy，but once it was a medicine．Today，chocolate can be a hot drink，a frozen dessert，or just a snack．Sometimes it's an ingredient（配料） in the main course of a meal．Mexicans make a hot chocolate sauce called"mole"and pour it over chicken．The Mexicans also eat chocolate with spices like chili peppers．
Chocolate is a product of the tropical cacao tree．The beans taste so bitter that even the monkeys say"Ugh!"and run away．Workers must first dry and then roast the beans．This removes the bitter taste．
The word"chocolate"comes from a Mayan word．The Maya was an ancient people who once lived in Mexico．They valued the cacao tree．Some used the beans for money，while others crushed them to make a drink．
When the Spaniards came to Mexico in the sixteenth century，they started drinking cacao too．Because the drink was strong and bitter，they thought it was a medicine．No one had the idea of adding sugar．The Spaniards took some beans back to Europe and opened cafes．Wealthy people drank cacao and said it was good for the digestion（消化）．
In the 1800s，the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao．It quickly became a cheap and popular drink．Soon afterwards，a factory made the first solid block of sweetened chocolate．Later on，another factory mixed milk and chocolate together．People liked the taste of milk chocolate even better．
Besides the chocolate candy bar，one of the most popular American snacks is the chocolate chip cookie．Favorite desserts are chocolate cream pie and，of course，an ice cream sundae with hot fudge sauce．
21．It wasDthat discovered sugar could remove the bitter taste of cacao．
A．The workers in a chocolate factory

8．How to deal with waste has been a problem since humans started producing it．As more and more people choose to live close together in cities，the waste-disposal（处理）problem becomes increasingly difficult．
During the eighteenth century，it was usual for several neighboring towns to get together to select a faraway spot as a dump site（垃圾填埋场）．Residents or trash haulers（垃圾拖运者）would transport household rubbish，rotted wood，and old possessions to the site．Periodically（定期的）some of the trash was burned and the rest was buried．The unpleasant sights and smells caused no problem because nobody lived close by．
Factories，mills，and other industrial sites also had waste to be disposed of．Those located on rivers often just dumped the unwanted remains into the water．Others built huge burners with chimneys to deal with the problem．
Several facts make these choices unacceptable to modern society．The first problem is space．Dumps，which are now called landfills，are most needed in heavily populated areas．Such areas seldom have empty land suitable for this purpose．Land is either too expensive or too close to residential（住宅区的）neighborhoods．Long-distance trash hauling has been a common practice，but once farm areas are refusing to accept rubbish from elsewhere，cheap land within trucking distance of major city areas is almost nonexistent．
Awareness of pollution dangers has led to more strict rules of waste disposal．Pollution of rivers，ground water，land and air is a price people can no longer pay to get rid of waste．The amount of waste，however，continues to grow．
Recycling efforts have become commonplace，and many towns require their people to take part．Even the most efficient recycling programs，however，can hope to deal with only about 50per cent of a city's reusable waste．
27．The most suitable title for this passage would beB．
A．Places for Disposing Waste
B．Waste Disposal Problem
C．Ways of Getting Rid of Waste
D．Waste Pollution Dangers
28．During the 18th century，people disposed their waste in many ways EXCEPT forA．
A．recycling it
B．burying it
C．burning it
D．throwing it into rivers
29．What can be inferred from the fourth paragraph？C
A．Farm areas accept waste from the city in modern society．
B．There is cheap land to bury waste in modern society．
C．Ways to deal with waste in modern society stay the same．
D．It is impossible to find space to bury waste in modern society．
30．The main purpose of writing this article is to．D
A．tell people a better way to get rid of the waste．
B．warn people of the pollution dangers we are facing．
C．call on people to take part in recycling programs．
D．draw people's attention to waste management．

18．Modern computer technology has made online friendship possible．Online friends are people who have known each other through the Internet．Are online friendships as beneficial as face-to-face friendships？Can people form strong relationships online？
When you use social networking websites and chat rooms，you can easily find people with interests and hobbies similar to yours．Making friends on the Internet is especially good for shy people who feel uncomfortable in social situations．It's often easier to share thoughts and feelings online．What's more，online friends can make people feel less lonely and help them solve problems．
Although the Internet can encourage friendship，it has a major disadvantage．It's much easier for some people to deceive others because they are not face to face．Online friends only tell you what they want you to know．They sometimes exaggerate（夸大） their good qualities and hide the less positive ones，so you can't be sure of what they really like．
There are different answers to the second question．Researchers surveyed 2，000families in the US．The results showed that over 40% of participants（参与者） feel as strongly about their online friends as they do about their offline friends．Researchers also found that it's not unusual for online friends to become face-to-face friends．However，there are many people who believe that it's not possible for people to have deep relationships with online friends．
People continue to express different opinions about online friendship．However，most of them would agree that face-to-face friendship cannot be replaced by online friendship．As one life coach says，"A social networking site should only be the‘add on'in any relationship．"
55．What is the second paragraph mainly about？D
A．Functions of friendship．
B．Signs of good online friends．
C．Ways to make online friends．
D．Advantages of online friendship．
56．The underlined word"deceive"in Para.3probably meansC．
A．praise
B．support
C．cheat
D．hurt
57．In most people's opinion，online friendshipA．
A．won't take the place of face-to-face friendship
B．are as important as face-to-face friendships
C．are better than face-to-face friendships．
D．will become face-to-face friendships

5．Being Authoritative （权威的） Parents
Phrases like"tiger mom"and‘‘helicopter parent"have made their way into everyday language．Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort，we might turn out children with bright futures．But is there anything wrong with a kind of"overparenting style"？
Parental involvement has a long history of being studied．Many of the studies，conducted by Diana Baumrind，a famous psychologist at the University of California，Berkeley，have found that a good parent is the one who is involved and reacts to her child in a positive way，who sets high expectations but gives her child independence．These"authoritative parents"appear to hit the sweet spot of parental involvement and generally raise children who do better academically，psychologically and socially than children whose parents are not strict and less involved，or controlling and more involved．Why is this parenting style so successful？
Authoritative parents actually help improve motivation in their children．Carol Dweck，a social psychologist at Stanford University，has done research that indicates why authoritative parents raise more motivated children．In a typical experiment，Dr．Dweck takes young children into a room and asks them to solve a simple puzzle．Most do so with little difficulty．But then Dr．Dweck tells some，but not all，of the kids how clever they are．As it turns out，the children who are not told they're smart are more motivated to solve increasingly difficult puzzles．They also show higher levels of confidence and show greater progress in puzzle-solving．
As the experiment suggests，praising children's talents and abilities seems to shake their confidence．Dealing with more difficult puzzles carries the risk of losing one's status as"smart"．Dr．Dweck's work strongly supports that of Dr．Baumrind，who also found that reasonably supporting a child's independence and limiting interference （干涉） causes better academic and emotional results．
The central task of growing up is to develop a sense of self that is independent and confident．If you treat your young child who is just learning to walk as if she can't walk，you reduce her confidence．Allowing children to make mistakes is one of the greatest challenges of parenting．It is easier when they are young．The potential mistakes carry greater risks，and part of being a parent is reducing risk for our children．
25．According to the passage，a"tiger mom"D．
A．helps her children realize their dreams
B．speaks her children's everyday language
C．places reasonable expectations on her children
D．pays close attention to her children's experiences
26．It is implied that controlling style of parenting mayB．
A．face more challenges of children
B．cause more problems in children
C．develop independence in children
D．lead to children's academic success
27．The example of the children doing the puzzles suggests thatC．
A．a good game plays a big role in training young minds
B．puzzle-solving can give children the motivation they need
C．overpraising makes children less motivated and confident
D．bright children usually show less confidence in difficult games
28．The last paragraph tells us thatD．
A．children should not be given much freedom
B．parents should not increase the risk of challenging
C．children should correct mistakes with the help of their parents
D．parents should allow their children to learn from the mistakes．
